METAL SHEET-FILING.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed March 28, 1908. Serial No. 423,838.

To all whom it may concern:

Be it known that I, MANLEY W; CLUxToN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Sheet-Piling; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in interlocking metal sheet piling designed for use in the construction of coflerdams, retaining walls for excavations and the like, and the invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

Among the objects of my invention is to provide an improved joint between the sections or units of a sheet piling wall designed to prevent the passage of water from one side of the wall to the other.

Further objects of the invention are to construct and arrange the piling units in such manner as to produce a strong and rigid wall and to provide improved interlocking guides at the margins of the units such as to facilitate the driving of the units.

The piling construction to which my invention is more particularly adapted embraces alternate simple and compound units, the simple units comprising web portions having flanges at their side margins designed for interlocking connection with the marginal parts of the compound units, and the compound units embracing rigidly connected, laterally spaced rolled shapes, between which are received the flanged margins of the simple units and having marginal flanges directed inwardly towards each other for interlocking engagement with the flanges of the simple units.

In the drawings :-Figure l is a perspective view of a fragment of a wall constructed with my improved sheet piling. Fig. 2 is a plan View thereof. Fig. 3 is a plan view of a modified form of the construction. Fig. 4 is a plan view of a further modified form thereof.

As shown in the drawings, 10, 10 designate the simple units, and 11, 11 the compound units referred to. Said simple units, as herein shown, have the form of commercial I-beams, being provided at their side margins with oppositely extending flanges 12, 12. The compound units are each herein shown as made of two channel bars 14, 14 spaced a suitable distance apart, with the marginal flanges 15, 15 thereof at each side of the unit directed towards each other and spaced such distance apart as to receive the webs of adjacent simple units.

My improvements relate to the means for rigidly connecting the members of the compound units, to means affording proper guiding connection between the interlocking parts of the simple and compound units, arranged to facilitate the driving of the units, and t0 means for affording water tight joints between the adjacent units of the wall structure.

In the constructions shown in Figs. 1 and 2 the connection between the members of the compound units comprises channel bars 16, 16, the webs of which extend transversely between the webs of the members 14: of said units, and the flanges 17 'of which fit against and are attached to the inner sides ofsaid webs of the channel bar members of the compound units. The webs of the connecting channels 16 are located at such distance inwardly from the flanges 15 of the lateral members of the compound units as to afford longitudinal spaces which receive the flanges 12 of the simple units 10. Said connecting channels 16 thus constitute, together with the marginal flanges 15 of the compound unit members, guides to guide each unit, while it is being driven from an already placed or driven unit. The connecting channels 16 also serve to confine or hold the interlocking flanges of the units flatwise together, thus giving rigidity to the wall structure and preventing inward collapsing or displacement of the wall' units relatively to each other due to unequal lateral pressure against the wall.

tached to the side members of the compound units through the medium of short bolts 18, 18, each extending through one of the flanges of a connecting channel bar and through the web of an adjacent compound unit member. If desired, said connecting channels may be fixed to the side members of the compound units by longer bolts 19 which extend through the webs of both members of the compound units and through the two flanges of a connecting channel resting thereagainst.

Said guid- -1ng and connecting channels 16 may be at- After a wall has been constructed by the use of the units described, the spaces within and inclosed by the members of the compound units are filled with a suitable pack,- ing material, such as soft clay, grout or the like, which isplacedin, said packing spaces when ina plastic or soft state and" closely fills the same. Said packingmaterial is of such a nature as to find its way between the flanges of the connecting channels and the webs. of-the. compoun unit members, and into; the; spacesbetween the interlocking flanges of the units and saidflanges and the websiofthe connecting channels, and to completely-fill said. spaces in a manner to prevent-the passage o f-water between the interlocking units.

2 web of each; deep flanged channel bar is arrangedadjacent:toand parallel with the marginal flanges 15 at one side. of the unit to afford: a space between said web and flanges to. receive one of the flangedmargins of an adjacent simple unit. The free margins of the. flanges21 extend towards the opposite flanges of said. unit towengage and guidethe flanges 12 ofthe adjacent simple unit.

In each ofthev constructions just described the guiding-and attaching channel bars constitute means by which the, membersof the compound unit are fixed rigidly together. They serve to give greatstrength and rigidity to thecomponnd-unit, compared to the dity to the. compound unit, compared to the metal employed, and also serve. to; provide an exceedingly rigidjoint between adjacent. units. 7

In Fig. 4: I5hfi VQShOVIlthe channel bars 25; arranged to serve only; as guide, channels, the members ofthe. compound unit being connected by bolts extending transversely through said members. and'guide channels. Asshown in said figurethe webs of said guide channels are arranged parallel to the webs ofthe members of the compound units, and are attached thereto by bolts 27. Flanges 26 of said channels are arranged closely adjacent t0 and parallel with the marginal flanges 15 of the side members of the compound units to providebetween said flanges spaces to receivethe flanged margins of the simpleunits. The fastening bolts 27 extend through spacing sleeves 28 which engage at their: ends thewebs of the guide channels and serve to hold the side members of the compound units spaced the pro er distance apart, the heads and nuts of said bolts preventing said members from spreading, as is obvious.

I claim as my invention 1; In interlocking metal sheet iling, a compound unitcomprising laterally separated channel b'ar side members having their flanges directed towards eachother, and a, flanged guide, bar coextensive with the channeled side. members extending be.- tween said side members inside the flanges thereof and reinforcing and connecting said sidermembers together, parts of said guide ppos ng: a d; fl ng s e ng: a n o form between the, same and said nges p s t r c e a d gu de the ged ma gins of an adjacent unit.
